TAKE-UP AND SPOOLING MECHANISM.

Application filed April 11, 1922. Serial No. 551,540.

To all "ll/7107M it may concern:

Be it known that I, CHARLES C. KRIEBLE, a citizen of the United States, and resident of Norristown, Pennsylvania, havev in vented certain new and useful Improvements in Take-Up and Spooling Mechanism, of which the following is a specification.

The invention concerns take-up and winding mechanism for knitting machines and particularly machines for making narrow fabric, like tape.

The invention consists in the features and combination and arnangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings Fig. 1 is a front view of a knitting machine embody.- ing my invention. Figs. 1 and 1 are views of details. Fig. 2 is a side view with parts in section and parts broken away.

In these drawings 1 indicates the knitting head; 2, the frame; 3' are ordinary take-up rolls, which are driven through worm gearing 1 and bevel gearing 5 from a shaft 6, driven by belt 7 and pulleys 8.

The fabric A passes from the knitting machine down around the under side of a guide 9 which is supported on a journal pin 10 fixed in the fixed bracket 11. From this guide the tape passes in flattened form over a guide roll 12, carried by an (arm or movable support 13, mounted on a rock shaft 14 jo'urnalled in the fixed bracket, said shaft having fixed thereto an arm 15, carrying a weight 16. This shaft also carries an arm 17, fixed thereto, having a belt tightener wheel 18, which bears on the belt 7. From the movable guide roll 12, the flattened tape passes between the take-up rolls 3, which are driven through the gearing including the worm above mentioned.

The rotation of the take-up rolls will be regulated by the belt tightener and the action of this on the drive belt will be regulated according to the tension of that portion of the fabric extending from the knitting head to the take-up rolls, for it will be observed that if the take-up rolls feed the fabric down between them at a faster rate than it is knit, and comes off from the needles, then the movable guide roll 12, will be pulled downagainst the action of the weight 1.6 and through the shaft 14 and arm 17, the wheel or sheave 18 will be retracted in a direction away from the belt 7 and this belt then will not impart its full driving power to the gearing and worm and consequently the take-up rolls will be driven at reduced speed and the tension of the fabric will be reduced because the downward feed of the tape be.- tween the rolls will be reduced or will cease, until the normal tension is reached, whereupon the take-up rolls will resume their action owing to the fact that the tightening of the fabric between the knitting head and-the take-up rolls will permit the guide roll 12, to rise under the action of the weight 16, and at the same time the belt tightener wheel will press the belt. 7 i

into firmer frictional contact with the lower pulley 8, thus causing the take-up rolls to be driven at their normal rate of speed. 1

The flattened tape, after passing between the take-up rolls 3, goes beneath a movable guide or roll 20, thence up over a fixed guide 21, from whence it passes down and around the under side of a travelling guide roller 22, thence over a rough surfaced drum or roll 23, andto the spool 24 upon which it finally is wound for delivery to the trade.

The winding spool is journalled in the lower ends of the arms 25, of a. forked frame 26, which is mounted as an attachment to the base ring 27, of knitting machine of standard pattern.

This attachment frame 26, carries, besides the removable spool upon which the tape is wound for the market, certain devices which control the winding operation and the spiral laying ofthe tape upon the spool, as presently will be described.

The spool is driven by a worm wheel 23,

the shaft of which is journalled in one of the arms 25, of the attachment frame, and this worm wheelis driven by a worm 31, loose in a shaft 29, which is journalled at its lower end in the bearing forming an extension of one of the arms 25. The worm is driven by a clutch, one member 32 of which is fixed to the worm and the other member 32 of which is on a sleeve carrying a cam collar 34, and a plain collar 35. This clutch sleeve 33, is splined to the shaft 29, to be rotated thereby, but to have movement longitudinally thereof to make the toothed part 32 engage or disengagethe toothed clutch member The clutch is of the full throw type and is inlUS llU

tended to be either all the way in mesh or all the way out of mesh, with the worm, so that there will be no knocking of the parts of the clutch teeth and undue wear thereon will be avoided.

The clutch is controlled by a lever 36 pivoted to one of the bracket arms at 37, and this lever carries a head or block 38, in which are mounted two pins 40, pressed outwardly or to the left, Fig. 1 by springs. When the lever 36, is turned so as to make its head or block with its spring pins recede from the clutch sleeve, said sleeve will fall all the way down and at once fully engage the clutch member of the worm so as to drive the latter. hen, however, the lever is turned in the opposite direction, the lower spring pin 40, will seat itself in the recess 34 of the-cam collar and as the clutch member continues. its rotation the incline 34; on the lower side of the said collar will ride up the pin and the clutch member will be thrown fully up so that its tooth will disengage the tooth v of the portion 32. The upper spring pin 40 will then snap into place beneath the upper collar 35, and the sliding clutch member will be held in its elevated position and will cease turning the worm and worm wheel until the clutch is again thrown in.

The shaft 29, extends up along the inclined frame or bracket attachment 25, its upper end being journal'led in a bearing 41, on the main frame of the machine and at its upper end it carries a bevel gear 42, meshing with a bevel gear 43, fixed in the main drive shaft 44 of the knitting machine. This shaft 29, therefore, is in constant rotation so long as the knitting machine is in operation.

The clutch controlling lever 36, is operated by a rod 45, the upper end of which is pivoted to a lever 46. This lever is pivoted to one of the side arms 25, of the bracket attachment and it carries at its rear end the guide or roll 20. This roll is supported in a loop of the tape, which as before stated, passes down from the take-up rolls, passes under roll 20 and thence up over guide 21 and down to the spool 24. Therefore, if the fabric tends to unduly lengthen between the spool and the take-up rolls 3, the guide roll 20, will move down and cause lever 46, to draw up on rod 45 and lever 36, with the result that the clutch member 32, 33, will be allowed to drop into engagement with the clutch member 32 and the spool will be turned to wind the fabric. but if, on the other hand, the take-up rolls 3, do not deliver the fabric fast enough to supply the spool, now in rotation, with fabric, the roll 20 with its lever 46, will be raised thus ushing down on rod 45 and setting the clutch lever 36 so that then the spring pins thereof will set themselves in position to relieve the clutch and hold it out of operation to prevent further winding of the tape on. the spool until the fabric is supplied properly thereto by the take-up rolls.

The tape is laid on the spool spirally and for this purpose the final guide roll 22, is journalled inthe forked lower end 47 of an oscillating arm 48, which reaches up to the top of the bracket attachment 25, 25*, where it is pivotally mounted at 49 to a boss on said bracket. This. arm therefore swings in an arc in a direction lengthwise of the spool and as the tape is guided by this roller 22. it will be directed to the spool. and laid thereon spirally.

For swinging the arm 48, it is provided with a pin to engage spiral cam members 50 on a step by step rotating drum 51, journalled in the arms 25 of the bracket.

It is driven step by step by a ratchet 52 and pawl 53, the latter being guided in a supplemental bracket 54 carried by the main bracket 25, 25 The pawl is retracted by a spring 55 and it is advanced to turn the cam drum by a cam disc 56, having cam inclines 57. This cam disc is driven by a sprocket wheel 58, a chain 59 and a sprocket 60 on the worm shaft and it will thus be seen that the connections just described are driven from the shaft 29, through the worm gearing. j i

The turning of the cam drum step by step swings the arm 48 with its tape feeding roll 22, back and forth, along the spool with the result that the tape is laid spirally thereon, from end to end.

The function of the sand paper covered roller is to lay the fabric smooth on the spool. The winding is done by a laying on action rather than by a pulling action, and the fabric is ironed out fiat by the action of the sand paper covered roll, which has suflicient weight for, this purpose. The fabric as it leaves the roll 23 passes at once between the said roll. and the spool and at once is acted on.

This roller consists of a metal cylinder of considerable weight. The sand covered surface prevents the tape from slipping along the roll away from the point where the tape contacts therewith, and the points where the successive portions of the tape first strike the said paper covered surface will be the corresponding points where these portions of the tape will be laid on the fabric spool.

The lever 46, with its roll 20 and the connections to the full throw clutch including the lever 36 andhead38, are so proportioned as to weight, that when the fabric lengthens between the point where the take-up rolls 3 are located and the winding spool, now supposed to be momentarily at rest, the roll 20 will fall and the clutch will be allowed to drop into working position to drive the spool.

The main take-up mechanism is mounted on a fixed bracket instead of being pivotally mounted as heretofore.

It will be noticed that the power for driving the main takeup rolls and also the spooling mechanism, is taken off from the main driving shaft of the machine, the former through the belt drive and the latter through the shaft 29. This main driving shaft turns the knitting head through a bevel gear.

It will be further observed that the attachment frame 25, extends downwardly and forwardly in relation to the main machine frame and the spool, together with its operating mechanism, is readily accessible.

The spool is mounted on a support con sisting of a shaft rod 61 which at one end is provided with a conical shoulder 62 and an enlargement 63, the latter bearing in a part of the bracket 26. This end of the supporting rod is provided with a finger wheel 64.. The other end of this rod receives a screw 65, Fig. 1 which is provided with a linger wheel 66. The rod passes through the shaft of the worm wheel and by turning the finger wheel (36 the rod is drawn longitudinally so that its conical bearing 62 will engage the end of the spool and the other end of the spool will be seated against the comcal bearing 67 on the shaft of the worm wheel.

In order to remove and replace a spool, the linger wheel 66 is turned to withdraw the screw 65 from engagement with the rod 61 and then the rod may be withdrawn by taking hold of the finger piece 64 and drawing it out towards the left and in inserting the new spool it is placed with its axis in line with the worm wheel shaft, and the rod 61 is then thrust into place, and the screw 66 is inserted and turned so that the spool will be drawn against the conical member 67 of the worm shaft to be turned by the said shaft. The train of connections for operating the cam 50 derive their power through the sprocket wheel (30 on the shaft of the worm wheel.

The pressure roller J3 is carried in arms 68 pivoted at 69 to bracket arms 70 as shown in Fig. 2. This pressure roll is rotated by frictional contact with the spool.

The spooling mechanism is mounted on the main frame and presents the spool well exposed at the front of the frame and the main supporting legs, where it is readily ac cessible.

It will be observed that the spool is driven by frictional contact between the face of the enlargement 63 at one end and the face of the worm wheel 28 at the other end.
